IMPROVEMENT IN TRUNK-LOCKS,

ro'ALL WHoM 1T MAY ooNcERN:

VBe it known that I, SERENO GAYLORD, of Chicopec, Hampden county, Commonwealth of Massachusetts, have invented a new and improved Chest-Lock; and I do hereby declare that the yfollowing isy a full and exact description thereof, reference heilig had to the accompanying drawings, and to the letters of reference marked thereon. In the'drawings- Figure I iskan interior view of my lock.

Figures 2 and 3, sectional views of the mechanism of thesame. f

This inventoivconsists of a -lock more particularly adapted to chests, trunks, &c., so arranged that the mechanism inside may be arranged in a nuniber of ways, requiring a di'erent for each new arrangement.

In construction I form my lock with two or more catches B B A A on cach'side offthe key-pin il. 'These catches are hung on pins 1 l, a little below and on each side of the key-pin a These catches rest upon and are guided by a piece, E, attached to the plate of the lock, and forming a stop-gn`ide for the catches. This piece E projects at each end at b b',and in the centre at c, being brought at these points to the same plane as that of the top of the catch, so that, when the back-plate or cover of the lock is put on,fit rests against ,these projections, leaving theint'errcning' spaces for the catches to work in. Attached to eaeh'of the catchcsA A and B B are steel springs ff', which :irc fastened in a suitable manner to the lower and outer edges of'the catches, and which press at their other ends against the projections b bron the ends of the piece E,n this arrangement they keep the catches pressed up against the middle projection c until forced back by the turning of the key. 'Beneath the lower ends of the catches A Il, Snc., are placed guards C and D. These are small pla-tes, with curves 'on their upper edges, centri-ng toward the key-pin, and serve the purpose of preventing the lock from being opened by the turning of a wrong key. These guards are slipped up'cn the'pnsl 1, each guard having two holes in for the purpose. These guides. when so placed, form rests for the lower ends of the catches, while the recesses in the piece E form rests at 'their bottom edges for the upperends of the catches on the saine plane.

By this 'means I obtain a iock'which can be arranged4 in as many different Vways as the combination and -arrangements'of the catches and guards can supply, and the catches are made ofdiierent widths and distances from the key-pin, so that a different key is required to open the lock 'each time it is arranged differently.

I In figs. Zand 3 is shown a section of the lock, with the catches and guards reversed, and on a line with -them is shown the key required 'to fit each new arrangement. The projections b b upon the piece E form stops shown.

and guards also for the catches, so that a key which may fitin other respects cannot tur-n around inside the lock.

And now having described lmy invention, what I claim as new, and desire to secure byLet'ters Patent, is 1. I` claim, in a. catch-lock, placing two or more catches A A B B on each side of the key-pin, and work ing onpins 1 v1 at their lower ends, the Adistances between the key-pin and key-bearings being different4 on the upper and lower catches, so that, by reversing the same, a di'erent lock may be formed, the parts arranged substantially4 as herein shown. i

` 2.l In combination with the above, the key-guards C and D, arranged substantially as and for the purpose SERENO GAYLORD.
